Most portable, easy to use setup, a serious grab and go. Binoculars great quality and spot on collimation upon arrival, scope body all metal including screw on/off dewshield beautifully finished. Focuser body a fine pebble finished heavy duty plastic with 4screw rack plate that adjusts to silky smooth function. Focuser tube is metal 2" dia. but only allows 1.25" eyepieces, rack/pinion gears all metal. Scope collimation at rear cell by eyepiece much easier than those with adjustments at front of scope. Tripod has same heavy black plastic at leg articulations but is heavy duty and should give long service with proper care, eyepiece tray twist locks in place, very nicely. Mount arm and base are cast aluminum with plastic trim/coverings and are easily adjustable and very smooth motion. Scope views are bright, really nice contrast on clusters, star fields, and nebulae--nicer than my 4" high quality SCT on such objects. Coatings are fully multicoated, flawless, splitting Castor at 80--over 200x shows diffraction pattern of high quality optics. The heavy duty cordura backpack has a plush finish on the inside, holds the entire set with padded adjustable partition between mount head and OTA, while tripod slips into a small pocket with straps holding it snug alongside. Also a large front zipper pocket for other items. So easy to use and enjoyable views, ready for the yard or travel to a dark site with ease. Included Bresser 20mm/70 degree eyepiece, giving 3 degree+ field of view, makes the scope its own big finder. I'd recommend adding a 6, and 15mm with a good 2x Barlow to cover most any viewing opportunity. My most used scope. Also an Explore Scientific lifetime warranty! Simply great combo at a fair price.
